WILLIAM HAYES ROGERS, OF KINGSTON, ONTARIO, CANADA.

A AXLE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 430,438, dated June1'7, 1890.

Application filed April 15, 1890. Serial No. 348,028. (No model.) i

To all whom it may concern.-

Be it known that 1, WILLIAM I-IAYEs Roo- ERS, a citizen of the Dominionof Canada, residing at Kingston, in the county of Frontenac and Provinceof Ontario, Canada, have invented certain new and useful Improvements inAxles for Vehicles; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to axles for vehicles. It is a well-known factthat metal axles, whether they are used by engines, cars, carriages, orwagons, are all subjected in service tocontinual jarring under more orless strain, causing vibration among the particles of the metal, whichtends to crystallize it, producing that kind of weakn ess which causesthe axle to be broken short off by some unusual strain.

The object of my invention is to construct axles of anykind of metal andfor every kind of vehicle that the vibrations cannot be so communicatedfrom one particle to another throughout any cross-section of the axle asto endanger such crystallization and consequent breaking.

To this end my invention consists of a vehicle-axle constructed ashereinafter described and claimed, reference being had to theaccompanying drawings, in which- Figure I is a side view of a portion ofa wagon-axle; Fig. II, a cross-section at the line :r; Fig. III, a sideview of a portion of a caraxle at the journal; Fig. IV, a cross-sectionat the line y; and Fig. V, a cross-section of a modification, allshowing my invention.

A represents the central portion of the axle, which I call the core. Itmay be of any kind of metal, formed either cylindrical or tapering,round, or many-sided. Around this core I place a series of staves B,neatly fitted upon the core, and preferably touching each other onradial lines D, and at suitable intervals, or covering the whole length,as different cases require, I place bands E tightly around the staves B.This may be most economically and securely done by heating the bands andshrinking them on. By this means the core and staves are united to forman axle, which may be turned in a lathe and otherwise manipulated asthough it were a single piece of metal; but I do not contemplate weldingor otherwise actually uniting the difierent pieces of metal, because ifthat were done it would produce a common piled-up faggot and result inmakinga single piece of metal. The outer surface of the staves may beround, as shown in Fig. II, or many-sided, as shown in Fig. V. In thelatter case the band E may be swaged into formon a properly-shapedmandrel.

It is evident that the particles of metal in the core and in the stavescannot be subjected to exactly like conditions of vibration, and

that any such vibration as tends to disintegrate the particles cannotpass in a direct line like a crack from one piece to another of thisaxle, and I think that the nature of the vibrations being continuallychanged by the changing strains due to the different stays on the corein revolving car-axles will tend to prevent crystallization, and thatthe same result will be found to follow in a more limited degree inthose axles which do not revolve, owing totheinharmonious vibration ofthecore and variously shaped and located staves. The advantages of anyconstruction which will render the axles of cars and other vehicles lessliable to be broken in service are obvious.

Having thus fully described my invention, what I believe to be. new, anddesire to secure by Letters Patent, is the following:

A vehicle-axle comprising a metallic core, a series of metallic stavesaround the core, and rings driven or shrunk upon the staves,substantially as shown and described.

In testimony whereof I aflix my signature in the presence of twowitnesses WILLIAM HAYES ROGERS. WVitnesses:
